Y cannot take 20 in lowest place
Because that isn't the lowest place. 20m is still above ground and sea level. The -70m is 70m below sea level.
Lowest place is not restricted to above ground/above sea level. It can be :
① above ground/above sea level
② on ground level / at sea level
③ Underground / under sea level
Lowest place is not restricted to above ground/above sea level. It can be :
① above ground/above sea level
② on ground level / at sea level
③ Underground / under sea level
So -35m cannot
-70m is lower than -35m
